The device for golf swing correction according to the present invention comprises, inter alia: a laser module ( 100 ) for generating and irradiating laser light; a support means ( 200 ) which supports the laser module ( 100 ) and of which one end is detachably attached to a face (F) of a golf club (including putters); a clamping means ( 300 ) which is provided on one end of the support means ( 200 ) and to which the laser module ( 100 ) is detachably secured; and an intimate fitting member ( 400 ) which is provided on one end of the supporting means ( 200 ) such that one surface of the supporting means ( 200 ) is secured fitting intimately against the face (F) of the golf club. Consequently, the present invention has the advantage that users can be made precisely aware of the swing path, and can themselves correct their golf swings.

TECHNICAL FIELD

The present invention relates to a device for golf swing correction, and in particular to a device for golf swing correction which can be selectively engaged at a head of a golf club and makes it possible for a user himself to check whether or not a user's swing is performed along an accurate track with the aid of a laser beam coming from a laser module.

BACKGROUND ART

A conventional device for golf swing correction is generally designed to focus on a function of indicating a swing line, and it is engaged at a shaft of a golf club.

The above device is characterized in that a laser beam coming from a laser module of a swing line indicator engaged at a shaft of a golf club goes straight alongside a shaft and indicates a target point.

The Korean patent registration number 10-0674029 discloses the construction of an apparatus for indicating swing and put line for golf.

The above conventional apparatus for indicating swing and put line for golf is designed to engage at a shaft, not a face surface when in actual use. The indicator is installed in such a way that the distance between the indicator and a laser point is spaced apart one meter maximally. The conventional indicator has a disadvantage in that an error value range might be large due to a viewing difference between users left and right eyes.

In addition, when a user multiple times rotates a laser module, a friction force between an outer surface of a rotation ball and an inner surface of a groove decreases, thus loosening their engagements.

As shown in the drawings, the device for golf swing correction according to a first embodiment of the present invention comprises a laser module 100 generating laser beam and emitting the same, a support pat 200 one end portion of which is detachably engaged at a face (F) surface of a golf club, a clamping part 300 to which a laser module 100 is detachably fixed, and a close engaging member 400 helping one surface of the support part 200 to closely fix at the face (F) surface of a golf club.

The laser module 100 has a function of generating and emitting a laser beam. Since the basic operation principle of the laser module 100 is known in the art, the descriptions on the generation and emission principles of the laser beam will be omitted.

The laser module 100 comprises a body part 110 formed in a cylindrical shape on the whole, an engaging part 120 inserted into the clamping part 300, a switch 130 turning on/off the generation and emission of the laser beam, and a guide protrusion 140 guiding the engagement of the laser module 100.

The body part 110 is formed in a cylindrical shape, with batteries and electronic parts being disposed in the interior of the body part 110.

The engaging part 120 is provided at a lower side of the body part 110 and has an outer diameter smaller than that of the body part 110, from which a laser beam is generated and travels to the outside via a lens (not shown of a lower side. In other words, the laser beam coming from the lower side of the laser module 100 travels outward and indicates a bottom surface or a target thing.

The switch 130 is protruded upwardly from an upper side of the body part 110. So, when a user pushes once the switch 130, laser beam is generated, and emits, and when a user pushes once more the switch 130, the laser beam is turned off.

The guide protrusion 140 is outwardly protruded from an outer surface of the engaging part 120. The guide protrusion 140 is formed to have a certain length in an upward and downward direction along the longitudinal direction of the laser module 100.

The guide protrusion 140 is provided at least one. In other words, it might be formed at a front side and a rear side or at a left side and a right side of the engaging part 120. The guide protrusion 140 is inserted into a guide groove 312 a which will be described below and serves to guide the laser module 100 to be engaged in place.

The laser beam (laser point) emitted from the laser module 100 might be formed in a “+” shape, a “−”shape or a “.” shape.

The support part 200 serves to support the laser module 100. One end portion of the support part 200 is detachably engaged at a face (F) surface of the golf club (including putter). In other words, each golf club is generally formed of a shaft (S) and a head (H). The lower end portion of the support part 200 is fixed to a face (F) surface of the head (H).

The support part 200 comprises an arch shaped engaging member 210 which comes into close contact with the face (F) surface of the golf club, and a support member 220 supporting the clamping part 300.

The engaging member 210 is rounded to have an arch shape as shown in the drawings. At both ends of the engaging member 210 are disposed the close engaging member 400 in a pair. The engaging member 210 might be formed in a stepped shape (when viewing from the above). The reasons for forming the engaging member 210 in a stepped shape are to prevent any interference with the shaft (S) when the support part 200 comes into close contact with the face (F) surface of the putter.

As shown therein, the support member 220 is extended upward from the engaging member 210. In other words, it protrudes vertically from the back of the engaging member 210 in an upward direction, thus supporting the clamping part 300.

The clamping part 300 is provided atop the support part 200. In other words, the clamping part 300 is rotatably installed at the support part 200. The laser module 100 is detachably fixed at the clamping part 300. As the clamping part 300 rotates, the laser module 100 rotates, so the direction of the laser beam coming from the laser module 100 can change.

The clamping part 300 comprises a fixing member 310 fixing the laser module 100, and an engaging member 320 facilitating the laser module 100 to be supported by means of the support part 200. The clamping part 300 comprises a fixing member 310 provided at a front side for the purpose of holding the laser module 100, and the engaging member 320 provided at a rear side (left side in FIG. 2) and engaged with the fixing member 310.

The fixing part 312 is formed to have a C-shaped cross section (when viewing from the above) and surrounds the engaging part 120. The fixing part 312 is made from a plastic material or something and is formed to have a certain elastic force from its shape. In other words, it is formed in a C-shape with its opening being able to be open by an external force.

At least one guide groove 312 a accommodating the guide protrusion 140 is formed at an inner surface of the fixing part 312. A guide groove 312 a selectively accommodating the guide protrusion 140, mentioned earlier, is formed at upper and lower sides.

In more details, a guide groove 312 a corresponding to the guide protrusion 140, respectively, is formed at the rear side and left and right sides of the inner surface of the fixing part 312.

The fixing part 312 is formed to surround more than half the outer surface of the engaging part 120 of the laser module 100 on the whole. At both left and right sides of the front end of the fixing part 312 are provided an escape prevention protrusion 312 b supporting for the laser module 100 inserted at an inner side of the fixing part 312 not to escape as shown in the drawings.

The insertion part 314 is formed in a thin rod shape and is installed to pass through the upper side of the support member 220.

The engaging part 316 is extended from the left side (FIG. 2) of the insertion part 314 and is formed of a mane thread. The engaging part 316 is thread engaged with the engaging portion 322 which will be described later.

The engaging member 320 comprises an engaging portion 322 engaged with the engaging part 316, and a rotation part 324 formed at one end of the engaging portion 322, thus facilitating an easier rotation control of the engaging portion 322.

The engaging portion 322 is a member into which the engaging part 316 is inserted and engaged. A female thread is formed at a groove open to the right side (FIG. 2) in the interior of the engaging part 316.

The rotation part 324 is formed in a circle shape larger than the engaging portion 322 in order for a user to rotate holding the same with hands. A plurality of protrusions shaped like embossing are provided at an outer surface of the rotation part 324 for the purpose of preventing slip.

The close engaging member 400 is provided at a lower side of the support part 200. The lower right surface of the support part 200 comes into close contact with the face (F) surface of the head (H) of the golfer club (putter) and is substantially fixed.

The close engaging member 400 is detachably engaged at the lower side of the support part 200 by means of an engaging bolt (B) or something and is of a permanent magnet. Now that the close contact member 400 formed of a permanent magnet is engaged at a lower side of the support part 200, the support part 200 is magnetically attached on a face (F) surface of the metallic golf club (putter).

The operation of a device for golf swing correction according to the present invention will be described. As shown in FIGS. 1 and 2, the clamping part 300, which keeps separated from the support part 200, couples the fixing member 310 and the engaging member 320. In this state, the clamping part 300 is engaged at the support part 200.

Next, the laser module 100 is inserted into the fixing member 310 of the clamping part 300. The opening of the fixing part 312 is open, and the engaging part 120 of the laser module 100 is inserted. As the laser module 100 rotates, the guide protrusion 140 is inserted into the guide groove 312 a of the fixing part 312, so the laser module 100 can be positioned in place.

Since the close engaging member 400 is already provided at the lower side of the support part 200, the lower side of the support part 200 is forced to come into close contact with the face (F) surface of the golf club (putter) as show in FIG. 3. The lower side of the support part 200 comes into close contact with the face (F) surface of the putter by a magnetic force of the close engaging member 400.

When the device according to the present invention is engaged at the golf club (putter), a user turns on the laser switch 130 and swings a golf club as usual. Since the laser beam coming from the laser module 100 emits alongside the shaft (S) from the bottom surface (P), so the user can accurately recognize the swing track.

FIGS. 4 to 6 are views illustrating the construction of the device for golf swing correction according to a second embodiment of the present invention. Namely, FIG. 4 is a perspective view illustrating a construction of a device for golf swing correction according to a second embodiment of the present invention.

The device for golf swing correction according to the second embodiment of the present invention, like the first embodiment of the present invention, comprises a laser module 100 generating laser beam and emitting the same, a support pat 200 one end portion of which is detachably engaged at a face (F) surface of a golf club, a clamping part 300 to which a laser module 100 is detachably fixed, and a close engaging member 400 helping one surface of the support part 200 to closely fix at the face (F) surface of a golf club.

The laser module 100 is the same as the earlier descriptions.

The support part 200 is formed of the support member 220 and the engaging member 210, but the construction is simpler as shown in the drawings. In details, the insertion part 314 of the fixing member 310 is inserted into the inner groove of the support member 220, and the engaging part 316 is vertical from the insertion part 314. The fixing member 310 is rotatably installed at the left end of the support member 220.

At the support part 200 and the clamping part 300 is provided a setting part 500 which guides in a settable manner the direction of the laser beam coming from the laser module 100 depending on the size (number) of the golf club. The device according to the second embodiment of the present invention is mainly attached at the wood or the iron. The setting part 500 allows the user to easily adjust the installation angle of the laser module 100 depending on the size (number) of the wood or the iron.

As shown in the drawings, the setting part 500 comprises at least one indication line 510 formed at a front surface of the support part 200, and an indication part 520 formed at a front side of the clamping part 300 and corresponds to the indication line 510.

The indication line 510 might be simply formed of a line and might be formed of a protrusion forwardly protruded or a groove which is grooved in a backward direction.
